DNA Stains
In gel electrophoresis, fluorescent nucleic acid gel stains are dyes used for DNA detection. When bound to DNA molecules and illuminated with UV or blue light, these dye molecules fluoresce brightly. Once the gel is stained, transilluminators are used to excite the dye molecules, which allow DNA to...
Hematopoietic Stem Cells
Hematopoietic stem cells (HSCs) can be found in bone marrow, peripheral blood, and umbilical cord blood, and are important in studies of blood disorders and blood-related malignancies. We provide a comprehensive set of tools for study of HSCs and their derivatives.
